In the CSS file, selectors in line 17-20 are aligning headings and data for columns containing numbers right. Is there a shorter or better way to target (select) them? Writing 4 lines for that feels like writing bad code.
Hi @user.dev and welcome to the community 
You could reduce all the left/right alignment rules to the code below, but I think that about the most reduction you could get.
tr :nth-child(2),
tr :nth-child(3),
tfoot th {
text-align: right;
}
tr,
tfoot :nth-child(2) {
text-align: left;
}
There’s another possibility to style entire columns, but only a few properties are supported (border, background, width, visibility). Therefore this wouldn’t work with text-align, but maybe it’s helpful in another situation: <colgroup> and classes on individual <col>s inside.
I hope that helps, 
Michael
